我是學霸：10分鐘愛上數學: Hello
作者: 項華 | 繪者： 安妮卡・布蘭多
數字是一個相當龐大的家庭，在這個家庭裡生活著很多成員。有整數、分數……我們最常用到的數字就是整數。
世界通用的數字叫作阿拉伯數字， 阿拉伯數字雖然是由阿拉伯人傳入歐洲的，但它們的發明者其實是古印度人。
不同地區的人們使用的計數符號也各不相同。除了阿拉伯數字，計數符號還有很多種表現形式。羅馬數字是最早的計數符號。
本書特色
用淺顥易懂又活潑的圖文說明數字形成「十分鐘愛上數學」。把世界變成原子、分子的遊樂場「瘋狂的化學」。把地球裝進背包裡「這麼好玩的物理」。程式、網路、人工智慧、大數據竟如此有趣「不能不懂的程式設計」。基因、遺傳……你不知道的生物袐密「生物有袐密」。開飯啦！食物是電「Hello機器人」。

Great lights, terrible assembly
Just got these and ran one night, lots to love about these: very high-quality and sturdy construction. Huge solar panel compared to every other solar light I've used or seen. Seems like high quality powder coated finish and everything fit together great (except see below). I would have given this 5 stars except for the facts that 1) the threading of the screw for the spike to stake assembly is total crap. The threads got messed up when they cut the parts and they didn't bother to recut the threads. It took me no less than about 15 minutes of frustration per light to get the damn things to thread together. Only 1 out of 9 lights easily thread together like you'd expect and 1 cross threaded and would not go together. For $80 a piece you'd expect perfection. 2) So. Many. Screws. Granted you get the benefit of a 3 part stake to adjust the height but it takes 6 screws to just assemble the thing. Need to change the battery? NINE, yes 9 screws to get at the battery. Also, the screws are soft and easy to strip so take great care not to over tighten. So I'd recommend the light based on the quality and performance, just prepare yourself for a frustrating assembly and battery change when the time comes.

Over two years and works great
I’m happy with the light, works great, easy to clean and wipe down, lasts thru most of the night.
It gets great sun in our coastal yard for 6-8 hours and when it’s cloudy it still works decently

Worth Every Penny
Color: Black 1-Pack
Outstanding quality. It does require some muscle to assemble and install. The corkscrew spike is big and goes into the ground more than a foot but that is great because it is securely anchored. Beautiful 2700K light that stays on all night at HIGH setting. Time will tell how it takes Florida weather.

Nice solar light
Color: Black 1-Pack
The Gama Sonic solar lights are the best, finally a solar light that stays on all night. I was tired buying the cheap solar lights and replacing them almost yearly and finally invested in the Gama Sonic lights. This is a quality built light I hope will last.
